Bowl not filled with vanilla (5)
I believe the answer is:
bland
'vanilla' is the definition.
(I've seen this in another clue)
'bowl not filled with' is the wordplay.
I cannot really see how this works, but
'with' could be 'and' and 'and' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bland that I've seen before include "Unruffled but unstimulating" , "Dull - tasteless" , "Boring" , "Flavourless" , "Insipid, vapid" .)
